TaxVig / Free federal gambling tax calculator
Sports betting taxes, worked out.
See what your betting adds to your federal tax, and whether to itemize. Next: import your bets, see them per bet and by session, and hand your CPA clean numbers.
New for 2026: the 90% loss rule. You can deduct only 90% of your losses now, capped at winnings. Win $100K and lose $100K, and $10K of winnings you never kept can still be taxed. Recreational bettors must itemize to deduct any of it.

Run your annual totals, or see the same bets counted two ways.
